OUTLINE:

DEFINITION:

DEFINITION ‘Haptics’ is derived from the Greek word ‘haptikos’ which means-”being able to come into contact with” THE SENCE OF TOUCH 4

INTRODUCTION:

INTRODUCTION Haptics, is the technology of adding the sense of touch and feeling to computers. A haptic device gives people a sense of touch with computer-generated environments, so that when virtual objects are touched, they seen real and tangible. Understanding and enabling a compelling experience of Presence not limited to "being there", but extended to "being in touch" with remote or virtual surroundings 5

TECHNOLOGY:

TECHNOLOGY Haptic interactions can be categorized into the different types of touch sensations a user can receive: Tactile feedback Force feedback 6

Tactile feedback:

Tactile feedback Refers to the sensations felt by the skin. It allows the user to feel things such as the texture of surfaces, temperature and vibration. 7

Force feedback:

Force feedback It reproduces the directional forces that can result from solid boundaries. E.g. the weight of virtual objects, etc. 8

Military Applications:

REMOVAL OF LENS SEGMENT :

Disadvantages:

Disadvantages Expensive Haptic interfaces can only exert forces with limited magnitude and not equally well in all directions haptic device position sensors have finite resolution. 25

CONCLUSION:

CONCLUSION The next important step towards realistically simulated environments that have been envisioned by science fiction authors and futurists alike. Large potential for applications in critical fields as well as for leisurely pleasures. Haptic devices must be miniaturized so that they are lighter, simpler and easier to use. 26
